SourceXtractor++, the next generation SExtractor
Dear SourceXtractorPlusPlus developers, Our sysadmin has attempted to install SE++ on our CentoOS cluster. He has installed the following astromatic solfware packages Alexandria.x86_64 2.18-1.el7 CCfits.x86_64 2.5-14.el7 Elements.x86_64 5.12-1.el7 SourceXtractorPlusPlus.x86_64 0.15-dev.el7...
Hello, sorry for this basic question, but we cannot activate for example the partition-multithreshold option from the configuration file (we must add --partition-multithreshold in the sourcextractor++ command line). I found...
Assuming you know beforehand that magnitude covariance (between n bands, say) are well captured by multivariate normal distribution N(v0, C) of central values v0, and covariance matrix C, and A^-1...
Hello, when using --background-value, the background map has the constant input level, as expected, but it seems that the modelling does not take it into account. Indeed, we should have...
GSL proposes [Levenberg-Marquardt with Geodesic Acceleration](https://www.gnu.org/software/gsl/doc/html/nls.html#levenberg-marquardt-with-geodesic-acceleration), which may be able to close the gap with LevMar. Would it be possible to add it as a `set_engine()` option?
`-ffast-math` enables by default `-ffinite-math-only`, which tells the compiler it does not need to worry about operations that involve NaN and Inf. As one of these optimizations, it may decide...
